nothin wrong with doin that, some just like the tree because it has valves built in.

i use the jb 142n pump with 2- 3/8" ports and a 1/4" port built in.

i use 3/8" to 1/4" yellow jacket hoses and 2 appion core tools on the service ports.

i dont use a tree, i use the setup that came with the pump, it works just fine, just make sure its leak free.

Same setup I use.

How do you connect your micron gauge to the CRT? With a short hose? I have had problems with the hose collapsing under vacuum and also I suspect it permeates badly. I can't get my Bluvac to hold steady, it always has a slight rise, around .1 micron per second. Never noticed a problem with my Thermal!

some units will not let this happen due to tight spots, sometimes i cant get both core removers on.

worst case i will put the micron gauge on the 1/4" port on the vaccum tree, i like it away from the vaccum, but it will go there before i add another hose to the equation, i try to eliminate all the connections i can.

Does your Micron gauge have a female fitting or do you use a hose to your crt?

surely you could get just a valve that had a swivel on each end? I have no idea where to look but it would be nice.

Just picked up two myself, the rubber gasket is smaller then normal though so it looks like it might have to be babied.
If using for vacuum i reccomend some Nylog on the gaskets.
